Difcourfe will prove , that this great Change is made 
without any Fermentation, or ar^y kind ot Fermenta- 
tion, in the moft tolerable and fober fenfe. 
I do not name a third Opinion from the quantity of 
Lympha that is now feparated from the Blood, becaule 
mOil of our Modern Phyficians do acknowledge, that 
that is a weakcaufe for lo great an cfTed: ; and it (hall 
appear, by and by, that whatfoever fo great a Difcharge 
might perform in the fame way we confider other eva- 
cuations ; that yet it cannot account for the Cure, in 
fo fbort a time, no more than they. So here are Con- 
fiderations taken from the foiid Parts, by making Pain 
of fome Benefit ; from the Liquors in the VefTels, by 
Fermentation, and the Liquors out of the Veflcls, by 
the difcharged Lympha : and yet not one of - them to 
anfwer the Phasnomenon , even fuppofing they were 
fpoke to the beft advantage. Here feems to be all the 
exaftnels imaginable , and even nothing left. Let us 
flare the queftion again. A Delirium which is the ef- 
feil of this quick Puifey which is Curd hy the Wounds of 
CantharideSy or a Blijier. 
The Pulfe is nothing but the fide of an Artery that is 
diflended, by a certain quantity of Blood that is deter- 
mined thorow its Cavity, by a certain motion at every 
time the Heart is Contracted, and that touches and 
beats up our finger when we lay it on a place where we 
may be fenfible of this affeQion in the Artery. We fay 
this Pulfe is more frequent, not fo much that it beats 
oftner than any other Bodies, but that it beats quicker 
in the fame Perfon when he is faid to have a Fever, than 
before, when he was reputed to be in perfefl: Health; 
fo that a Phyfician is oblig'd to know the natural Pulfe 
of every Perfon, before he can judge by the Pulfe, that 
any one is Sick. And how that may be done, I have 
ihow'd at length, in a Book fome time ago. Howfbever,
